I have the "recommend" button in red square on left of my page, however, it seems to be doing no good there....rarely gets clicked. Should I just delete that specific part from my index page? I mean, what good is it? Anyone else use one to their advantage? It's still a mystery as to the value of these things.
I'd definitely leave it in. It's not like it looks out of place on your page. It could help you gain more readers/traffic through Facebook.
It all depends on what you are looking to go. Everything has a value but some tools or options are pointless to some. Everything depends on your goals or what you are trying to do.
